Borderlines

Name the realms on a blank map across three ages and watch how the borders shift from era to era.

How to play

The map starts unlabelled. For each era, select a region and assign the realm that controlled it, then switch to the next age and do it again. Part of the challenge is reading how the borders redraw between eras. Complete every era for the full score.

• Click a region on the map to select it
• Choose its controlling realm from the answer palette
• Switch eras to label the same map at different points in time
• Use Check to score the era and Clear Era to start it over

Controls

• Desktop: click a region, click a label, use the era tabs and the Hint/Check buttons
• Phone & tablet: tap regions, labels and era tabs

Tips & strategy

• Anchor on the realms you know first, then deduce neighbours from the borders around them
• Compare eras — a region that changed hands is exactly the kind of border the game rewards spotting
• Hints help on tough regions; Easy, Medium and Hard change how many realms share the map
